Abstract

A strip cutting unit(3) immediately precedes a holder(4) which supports cut strip sections(2a) and moves each to a lower splicing position. In the lower position the leading strip edge(16) to be spliced is located in a specific position relative to the trailing edge(13) of a previously spliced section(14) onto which it is to be spliced in an immediately adjacent splicing unit(5). The holder (4) is a stroking unit which moves linearly in a vertical direction or makes a swiveling movement in the vertical direction. In its upper position the holder supports a strip section(2a) which is moved by a conveyer into the cutting position. Strip sections are held in position during and after cutting by a suction system. A transporting system, comprising parallel conveyers, for conveying spliced strip sections(14,15) extends into the working area of the strip holder in its lower position, the strip holder also comprising parallel sections. In this position the holder upper side is either aligned with or lies below the conveyer transporting plane. Sensors(18), particularly light boxes, detect the rear edge(13) of a previously spliced strip section(14) and the spliced section conveyer operates in response to the sensor. The sensors and splicer unit can move as a unit. Movement(H) of the splicer unit is horizontal relative to the holder. A sensor(19) records the position of at least one long edge(20) of the strip to be cut and the splicing unit(5) is positioned accordingly. Clamps(17) hold the previously spliced strip section in the splicing unit. An independent claim is included for a process for manufacturing a continuous strip from adhesive, preferably textile cord, strips in which a strip section is cut from a fed strip and a holder moves the cut section to a lower splicing position in which the edge to be spliced is automatically positioned relative to the edge of a previously cut strip and then spliced onto it.

The present invention relates to an apparatus for cutting and splicing band portions of sticky bands, in particular cord bands, preferably textile cord bands. The device comprises a cutting device and a joining device, the cutting device comprising a conveying device associated with moving the band to be cut through the cutting device, the joining device already joining the edges of the cut band portion. To the edge of the band part.

By means of the device of the above-mentioned type, it is possible to produce bonded belted bands, in particular cord bands or preferably textile cord bands, which, for example, in the case of textile cord bands, for example, tire carcass Is needed in the tire industry to manufacture). In the known device, for example, a viscous band crosslinked together with textile fibers is drawn by a conveying device from a large band roll and pulled through the cutting device by the conveying device. A cutting device, for example a cutter, cuts the band portion to a defined length. The band portion thus cut is transferred to a conveying device, generally a band conveyer, and laterally conveyed to an adjacently placed bonding device, where the rear edge of the already bonded band portion is easily lowered so that the new band to be joined. The front edge of the portion can be moved above it. The joining device is then activated so that the two band edges are joined in an overlapping state.

A certain amount of time is spent in connection with transferring the cut band portion from the cutting device to the bonding device, which consumption negatively affects the maximum stroke time or cycle time of the device. Nevertheless, in the known arrangement, this horizontal conveyance carries the band portion cut by the joining device which is adjacent but spaced relative to the cutting device so that the two edge portions of the band portion to be joined here in particular This is necessary to overlap them.

It is therefore an object of the present invention to provide an apparatus which can increase the stroke time or cycle time.

In order to achieve the above object, according to the invention, in the device of the type mentioned at the outset, a receiving device directly connected to the cutting device is provided for the cut band portion, which receiving device places the band portion in a low bonding position. Moveable between an upper position and a lower position to move, wherein the edge to be bonded of the band portion at the low bonding position is defined in relation to the edge to be bonded of the already bonded band portion present in the bonding device directly connected to the receiving device. It is proposed to be located at.

In the device according to the invention, the bonding device is integrated into the cutting device, the two devices being connected directly to each other via a receiving device connected therebetween. Through the receiving device whose height is adjustable between the upper position and the lower position, the cut band portion is received in the upper position and moved to the lower bonding position. In the joining position, the cut band portion or the band edge to be joined of the cut band portion is automatically positioned with respect to the rear edge of the already joined band portion in a predefined positional relationship which immediately following the joining process. The rear band edge is present in the joining device, and the band edge to be joined of the cut band portion is automatically moved in a defined state, preferably in an overlapping state, when moved to the lower joining position by the receiving device. do. Of course, not only overlapping joining is possible, but also crash contact joining can be done, for which the lowered band edge of the band portion to be cut and joined for the second band edge when the receiving device moves to the lower position. It is automatically placed in contact so as to collide directly.

In the device according to the invention, in which the joining device is integrated into the cutting device and these two devices are connected via a direct receiving device, the transfer step by means of a conveying belt and the band to be joined, which take the same time as in the prior art described in the introduction. Subsequent overlap or positioning of the edges is omitted. Rather, the movement of the receiving device with the vertical movement component is simple and made in the shortest time, so that the band portion can be switched from the cutting device directly to the bonding device, and the two edges are automatically and precisely defined with respect to each other. Can be set. Since the joining process can be made in essentially shorter short time after the cutting process, the stroke time or cycle time can be compared to the devices known so far, which consist of a separate cutting device and a separate joining device connected via a conveying belt as described above. Will be increased. While yields of approximately 20 splices per minute are achieved with known systems, the device according to the invention can achieve up to 27 splices per minute while maintaining excellent positioning and preset tolerances with respect to the band edges. have.

Here, the receiving device can carry out pure vertical movement, ie the receiving device can be moved vertically from the upper position to the lower position. It is also contemplated to operate pivotally from the upper band receiving position to the joining position, ie the receiving device formed by the reciprocating device in each case can pivot between two positions and reciprocate. The movement path can be set to the shortest distance in each case after the two devices are optimally positioned relative to each other since the bonding device is integrated in the cutting device, so that a movement path of several centimeters can be realized. What is important here is that, taking into account the required working area of the bonding device, it is necessary for the cut band portion to move a few centimeters lower with respect to the plane in which the band portion already bonded is present.

The receiving device, which can be formed as a reciprocating table, already supports the band portion to be cut, which is moved on the receiving device by the conveying device, preferably in the upper position, so that the band portion to be cut is not freely positioned at least during the cutting. It does not sag. Each arbitrary conveying device can be used as the conveying device, in particular in the device according to the invention a conveying device as disclosed in German patent application DE 101 13 379 is used, which is also clearly referred to. In the case of the conveying device or the moving device, the front band edge is horizontally movable and in the device according to the present invention is gripped by the tongs movable on the receiving device and released during cutting, so that the cut band portion is clamped. Release from being able to be supported only on the receiving device.

Although the path from the cutting position or the cutting plane to the bonding position or the joining plane is very short, in order to maintain the required tolerances and positioning accuracy, the receiving device is at least after the cutting has been made, preferably even while the cutting has already taken place. It is preferable that the band portion is configured to fix the band so that the band is continuously fixed not only on the conveying device, ie the tongs as described above, but also on the receiving device. It is also conceivable to use any fastening means, but preferably suction means are used, ie a vacuum is generated on the receiving device which sucks the flat band portion onto the receiving device.

In order to pull the joined band portion, ie the belt-like band, a conveying device is preferably provided, in which the conveying device extends up to the working area of the receiving device, the upper side of the receiving device supporting the band portion. Is at or below the conveying plane of the conveying device at the lower position of the receiving device. When the receiving device is moved to the lower position, the band portion to be cut and now joined is automatically transferred onto the conveying device, the upper side of the conveying device defining the joining plane since the already joined band portion is supported thereon. The fixing of the band portion on the receiving device, for example via vacuum, is released when the delivery is made onto the conveying device as above or is automatically removed when the delivery is made. After the joining is made, the joined portion is pulled through the conveying device, and the receiving device is immediately moved back to the upper receiving position, since the moving part is now open again by discharging the band portion to which the joining is discharged. Here, it is preferred that the conveying device consists of a plurality of parallel conveying belts and / or the containing device consists of a plurality of parallel receptacles or table parts, as well as for reliable as well as delivery. This configuration enables each component of the two devices to be moved into each other.

Since the two band edges are bonded exactly when positioned correctly with respect to each other, preferably at least one sensor element, in particular a light barrier, is provided for detecting the rear edge of the band portion already bonded. The operation of the conveying device or conveying devices for conveying the joined band portion is in accordance with sensor detection. The rear edge is always located at a defined bonding position in the bonding device, as the sensor element and the detection-controlled movement operation allow for a very accurate and reversible positioning of the rear edge. Such material conveying systems using the sensor element and the conveying device in connection with the bonding device are for example disclosed in German patent DE 101 19 508, which also clearly refers to the patent.

It is particularly preferable for the bonding device to be movable in the horizontal direction with respect to the receiving device, for adjusting for various band widths and thus for adjusting for various bonding positions. This horizontal movement, however, is made not only for the intended adjustment of the known change in width but also for the detection of a change in the desired position of the longitudinal edge of the tacky band, which is preferably drawn from the large roll. In order to enable the joining device to always be correctly positioned with respect to the introduced edge of the band portion to be joined, a particularly preferred embodiment of the present invention is to provide a detection device for detecting the position of at least one longitudinal edge of the band to be cut. Suggested use, the bonding device can be positioned according to the detected edge position. In operation, the transport device pulling the bonded band portion is always moved on the same path. If the position of the longitudinal edge of the pulled tacky band is changed, the positional setting becomes inaccurate due to the deviation of the edge position. To compensate for this, since the exact position of the band edge to be joined which is lowered through the receiving device and placed in the bonding device is always known by longitudinal edge detection, a correction is applied to the bonding device in the same transport path. Here, after knowing the typical band width, it may also be considered to detect the two longitudinal edges of the band being pulled so that a conformance test can be carried out. While the joining device supported by a suitable linear guide and drive device is operatively moved, if the rear band end remains fixed in the joining device, the joining device is moved by a few millimeters during the position correction. In order to maintain the positional relationship of the bonding device or bonding bar with the sensor element or sensor elements used to detect the rear edge of the bonded band portion, the sensor element or sensor elements are preferably moved together with the bonding device. Can be.

Finally, it may be proposed that the cutting device and / or the joining device is provided with a band clamping element for fixing the band or the joined band portion as needed. The clamping element is a suitable retaining device in the form of a correspondingly driven stamp or block. In particular, a band clamping element (preferably a plurality of separately actuable clamping elements as disclosed in DE 101 19 508 above), which is provided for fixing the joined band portion and which is included in the joining device, each has an associated sensor element. As it can be driven through, accurate positioning and clamping of the band portion can be implemented.

The invention also discloses a method for producing a belt-like band of adhesive bands, in particular cord bands, preferably band portions of each band bonded together of a textile cord band, which method is carried out by means of a cutting device via a cutting device. The band portion is cut from the transferred band and moved to a lower joining position relative to the cutting position by a receiving device directly connected to the cutting device, where the edge to be joined of the band portion is directly connected to the receiving device. It is characterized in that it is automatically positioned in a defined positional relationship with respect to the edge to be joined of the already joined band portion existing in the two band portions.

The movement of the cut band portion by the receiving device is a pure vertical movement, ie the receiving device and the band portion moved therewith are guided in a vertical movement directly from the top to the bottom. Alternatively, pivotal movements or parallelogram movements including vertical movement components are also possible to move the band portion to a low bonding plane. Here, by means of the conveying device, the band moved onto the receiving device present at the upper band receiving position is already supported on the receiving device during the cutting and preferably already fixed on the receiving device during the cutting, in particular Inhalation through the inhalation device is preferred.

In addition, the position of at least one longitudinal edge of the band to be cut is continuously determined by the detection device, and the bonding device is preferably positioned through horizontal movement relative to the receiving device according to the detected edge position. In order to maintain the required tolerances and to ensure an optimal cutting process and / or joining process, the band portion is finally fixed through the band clamping element while the band is being cut and / or the band portion that has already been joined just before It is proposed to be fixed through the band clamping element while the band portion is being joined or while the joining device is displaced in the horizontal direction.

Other advantages, features and details of the invention are disclosed by the embodiments and figures described below.

1 and 2 show, in schematic form, an apparatus 1 according to the invention for cutting and joining an adhesive belt-like cord band 2 drawn from a roll not shown in detail as a calender material. The device 1 comprises a cutting device 3, a receiving device 4 directly connected thereto and a joining device 5 directly connected thereto, which are arranged or integrated in a common multi-part frame. Only the essential device components necessary for understanding are shown, and other components such as device frames, linear guides, drive units, etc. are not shown in detail for clarity.

In the case of the illustrated embodiment the cutting device 3 is shown as a cutter with an upper cutter 6 and a lower cutter 7, the upper cutter being moved down for cutting as shown by a double arrow (arrow) (A)). The cord band 2 is drawn through the conveying device 8, for example as disclosed in German patent application DE 101 13 397, and pulled between the cutting devices 3. The conveying device comprises a shrinking gripper 9, which has a band gripping position shown in FIG. 2 (shown on the right in FIG. 2) and a release position in which the pulled and cut band is released (FIG. 2). Can be operated horizontally, as shown by double arrows B). By means of the conveying device the cord band is passed through or pulled to the cutting position, the cord band being two vertically movable as shown by arrow C and preferably formed as a clamping block. It is present between the band clamping elements 10. When the cutting position is reached, the upper cutter 6 is operated downward to cut the cord band 2 so that a cut band portion 2a is obtained, which band portion 2a is placed on the receiving device 4. Supported, the band portion 2a is preferably already supported on the receiving device 4 during cutting. The receiving device is formed as a vertically movable reciprocating table as shown by arrow D, ie the receiving device is vertical between the raised upper position in which the band portion 2a is accommodated and the lower delivery position described below. Can be moved to. The receiving device 4 here consists of a plurality of separate receiving parts 4a in the case of the illustrated embodiment, the receiving parts 4a being transported in the lower position as shown by the dashed line in FIG. 2. Inserted between each conveying belt 11a of 11, each conveying belt 11a of the conveying apparatus 11 is used to pull the joined band.

Since the receiving device 4 is movable vertically as described above, there is provided a suitable drive mechanism, for example a crank mechanism, driven through a servo motor or a pneumatic drive device or a hydraulic drive device or the like, which is not shown in detail. .

By vertical movement of the receiving device 4, the band portion 2a is moved from the upper cutting position to the lower bonding position, which is shown in FIGS. 1 and 2 and indicated by an arrow E. FIG. In the joining position, the band portion 2a is supported on the one hand on the upper surface of the carrying belt 11. On the other hand, the band portion 2a already exists inside the operating region of the bonding device 5 or the bonding bar 12 shown in FIG. In the adjacent operating region of the joining device 5 or the joining bar 12, there is a rear end or a back band edge 13 of the band portion 14 already bonded, the band portion 14 already bonded. Part of the belt-shaped band material 15 which is composed of a plurality of respective band portions.

Through the vertical downward movement of the cut band portion 2a, the band portion 2a is moved to the adjacent operating region of the joining bar 12, and as shown in FIG. 2, the front edge 16 of the band portion 2a. ) Overlaps with the rear edge 13 of the band portion 14 already bonded. In other words, when the band portion 2a is lowered onto the carrying belt 11a through the vertical lowering movement of the receiving device 4, the band edge to be joined of the band portion 2a is already automatically joined to the joining device or joining bar. It is present in the operating area of 12 and is in contact with the second band edge to be automatically joined at the joining position or overlapping in some embodiments. Since the joining process can now begin immediately, the joining bar 12 is correspondingly moved as shown by arrow F, which joins the joined band material 15 as shown by arrow G. The same applies to one or more band clamping elements 17 which are secured to the device. Also shown in FIG. 1 is at least one sensor element 18, preferably in the form of a suitable light blocker, which sensor element 18 is rear edge 13 of the bonded band being pulled through the conveying device 11. Is used to detect). This allows control of the clamping element 17 to secure the joined band portion 14 with the rear edge 13 in an optimal position with respect to the joining bar 12. As mentioned above, the bonding device 5 together with the conveying device 11 and the sensor element 18 are part of a material conveying system, which is disclosed in German patent DE 101 19 508.

A bonding device 5 comprising a sensor element 18 disposed in a fixed position relative to the bonding bar 12 may be operated horizontally with respect to the receiving device 4 as shown by the arrow H in FIG. 1. Can be. That is, it is possible to position the bonding apparatus 5 or the bonding bar 12 in arbitrary positions with respect to the accommodation apparatus 4. This makes it possible to cope with various positions of the band edges to be joined of the newly conveyed cut band portion, so that the edges are optimally positioned relative to each other. For this purpose, there is provided a detection device 19, preferably a camera (for example a CCD camera), which is used to detect the longitudinal edge 20 of the belt-shaped cord band 2, and an evaluation device for the camera information. Is connected here. As soon as the edge deviation, ie the lateral offset is determined, the joining device 5 together with the sensor element 18, correspondingly with the rear edge 13 clamped, to compensate for the position deviation. It is moved in the horizontal direction. This ensures that the band portion 2 with the band edges shifted in a substantially horizontal direction is optimally positioned with respect to the rear edge 13 of the band portion 14 already joined despite this shift. As an alternative to the movement of the bonding unit, it may be considered to correct the detected edge misalignment by correcting the edge position before or after passing the cutting device through the displacement of the cord band or band roll.

3-10 with respective FIGS. A and b show various operating steps of the device according to the invention. FIG. A here shows the device diagram according to FIG. 2 and FIG. B shows the device diagram according to FIG.

3A and 3B show the device in its default position. The cutting device 3 is open, the upper cutter is moved upwards, and the shrink gripper 9 is immediately in the position of the cutting device area to clamp the front edge of the cord band 2. The band clamping element 10 is open, and the lower clamping element 10 which easily raises the band end so that the shrink gripper 9 grips the band edge is in the lower position and the upper band clamping element is in the upper position. . The receiving device 4 is likewise in an upper position, the already bonded band part 14 is clamped through the band clamping element 17 in the bonding device and the bonding bar is in the raised position.

In the next step shown in FIGS. 4A and 4B, the shrink gripper 9 is moved through the cutting device 3 by the required width or the band to be cut is pulled through the cutting device 3. Since the drive of the shrink gripper 9 is preferably through two axes, various partial angles can be realized with respect to the material. During this pull movement the cord band 2 is pulled on the receiving device 4, ie on the reciprocating table. The detection device 19 in which the processing unit is connected and fixed in position measures the position of the longitudinal edge of the cord band drawn during the pulling process. As the edges are thus introduced, the bonding device 5 is displaced horizontally with the clamped end 13 of the band material 14 already bonded, so that the desired preset overlap length or edge position can be obtained. have. However, if it is ensured that the code band 2 is always supplied with the required tolerances, the use of a detection device is not necessary.

In the next step shown in FIGS. 5A and 5B, the band clamping element 10 of the cutting device 3 is moved to the clamping position to fix the cord band 2, and the cutting device 3 has two cutters 6 , The band portion 2a is cut under the peristaltic movement of (7). It should be understood here that the two band clamping elements 10 are not necessarily required to cut the material. However, the two band clamping elements 10 are useful for improving the accuracy of the band portion. Likewise, it is not necessary to use an impact cutter as shown in the figures, but alternative cutting devices, for example circular gripper cutters or circular knife type cutters, may also be used.

During the cutting process, as shown by the arrow, the shrink gripper 9 is released and withdrawn to the rear, so that the cut band portion 2a is released from the shrink gripper 9. The upper cutter 6 cuts through the material and then moves back to the upper initial position. After cutting the band portion 2a is located on the receiving device 4. The receiving device is operated in vacuo, ie the band portion 2a is already sucked in and fixed while the cutting is taking place and remains fixed during the downward movement described below. The suction is not necessary but is used to maintain the required tolerances, particularly when high working speeds are considered.

Next, in the steps shown in FIGS. 6A and 6B, the receiving device 4 is moved downwards, so that the front band edge 16 to be bonded of the band portion 2a is attached to the rear edge of the band portion 14 already bonded. 13) so as to overlap a predetermined amount, and at the same time to the conveying belt (11a, 11b). In order to implement the set overlap length, the bonding device 5 is moved to the required position for this if necessary.

As soon as the receiving device 4 leaves the upper position, the retracting gripper 9 is moved back to the receiving position between the two cutters 6 and 7, and then immediately clamps the cord band edge to pull the next band. It becomes possible. The lower band clamping element 10 is also moved upwards, which forces the upper band clamping element 10 to be pressed, as shown by both arrows in FIG. 6A. This allows the cord band 2 to be raised by the lower cutter 7 on the edge side, so that the shrink gripper 9 can also grip the cord band 2 by lowering it on the edge side. At this time, the shrink gripper 9 is moved into the cord band to be blocked. Since the two band clamping elements 10 are opened after the shrink gripper 9 is blocked, the cord band is clamped only by the shrink gripper 9.

In the next step shown in FIGS. 7A and 7B, the joining process is now carried out, the joining bar 12 is moved from the stop position to the operating position, and the band edge 16 is placed onto the band edge 13 positioned below it. Firmly pressed, the two band portions are thus joined together.

In the next step shown in FIGS. 8A and 8B, under the drive of the conveying device 11, the belt-like band material 15 which is longer by the length of the band portion 2a immediately joined is pulled out. To this end, the band clamping element 17 of the joining device 5, which was holding the band material 15 up to this point, is opened, and the conveying device 11 passes the band material 15 through the joining device 5. To carry.

As described above, the conveying device 11 consists of respective conveying belts 11a, also called belt tracks, each conveying belt 11a being arranged between the respective receiving portions 4a or the receiving portion 4a. ) Between each other. Each of the conveyance belts 11a is driven through a common drive shaft. The conveying belt 11 is preferably driven in vacuum to fix the bonded band material 15 during conveyance, which vacuum fixing is not required in principle for the original process but is achieved by the apparatus according to the invention. This is desirable when considering the highest possible work speeds and accelerations.

During the transport in this step, a new shrinking process of the shrinking gripper 9 has already been started, and the band material is newly transferred into the cutting device 3. The timing for initiating the shrinking process is variable. Depending on the width of the band portion to be pulled, the point at which the receiving device 4 is in each case in the upper position at the end of the pulling process to ensure that it supports the cord band pulled by the shrink gripper 9 at the end of the pulling process. The pull is made exactly at. This prevents the material from sagging in a free state, because this sag causes inaccuracies in some cases.

The rear edge 13 of the bonded band material 15 in the next steps shown in FIGS. 9A and 9B is aligned with respect to the bonding device. As described above, a sensor element in the form of, for example, a light shield 18 for detecting the material end is disposed between each conveyance belt 11a. The sensor element or light shield is in a released state when the material end, ie the rear edge 13, is carried through the sensor element or light shield. A band clamping element 17, preferably in the form of a retaining pin, is associated for each sensor element 18 in the bonding device 5, which clamping element 17 is in the released state of the light blocker 18. Moved to clamp the material in the bonding apparatus 5. The transport belt 11 continues to move until all the light blockers 18 are released or all the band clamping elements 17 are moved downward. The continuous movement of the conveying belt 11 thus ensures that the material edges 13 at the end of the band material align exactly linearly after optimum clamping is made locally through each band clamping element 17. do. Ideally, all light blockers 18 are released at the same time when the band edges are exactly straight.

After the band material has been placed in the bonding device, the receiving device 4 is now at the end of the pulling process, as previously described with reference to FIGS. 8A and 8B, once the band has been discharged and the vertical path of travel is again open. It is moved upward again to support the cord band 2. When the receiving device 4 is placed in the upper position shown in Figs. 4A and 4B, the next cycle is started.

Finally, the steps shown in Figs. 3 to 10 are carried out partly in sequence and partly at the same time in one cycle, and the control of each part is made in consideration of the optimum working process as quickly as possible. Should understand.

According to the present invention, there is an effect of providing an apparatus for cutting and joining a band of sticky bands, in particular cord bands, preferably woven cord bands, which can increase stroke time or cycle time.
